Fig.- 9 is an endview, as viewed from theleft, of the portion of the apparatus illustrated in Fig. 8. Fig. 10 isa plan View of parts not shown in Fig. 9, but situated at the right ofthe parts shown in said Fig.9. Fig. 11 is a derail plan view of aportion of the apparatus not so specifically shown in Fig. 1, and Fig.12 is a vertical sectional view taken in the line y y of Fig. 11.

Supported in suitable bearings a is a revoluble hollow sleeve A, whichmay be revolved by a bandewheel ct or other suitable means and which hasfast upon it a spur-wheel 1). Extended from the end of this sleeve isathe inner layer of the tube is to be formed.

Fast axially at one of its ends to the inner end of the sleeve is amandrel 0, upon which thematerial is wound in the production of the tubeand the diameter of which determines the internal diameter of thefinished tube. This mandrel'is made detachable from the sleeve in orderthat mandrels of difierent diameters may be used according as tubes ofdifferent internal diameters are to be made. Arranged in due relationwith the opposite end of the mandrel to sever the tube ata point beyondsaid end is the cutting-0d mechanism by which, as hereinafter explained,the continuous tube is severed into sections of the lengths desired. Themandrel being fast to the sleeve, as explained, it necessarily rotatestherewith.

The ribbon d, of paper, from the reel 13 passes lengthwise through thesleeve and makes its exit from one side of the interior thereof to andupon the adjacent part of the mandrel. A spring 1; is arranged to pressupon the ribbon as it passes to the sleeve inorder to hold the ribbonunder proper tension.

Supported in a fixed annular bearing 6, suitably alined with the sleeve,is a revoluble annular head A, which has at one side and fast to it anannular spur-gear f. By means of a spur-pinion c this spur-gear fconnects witha spur-wheel f on a counter-shaft g, which, supported insuitable bearings, is below and parallel with the sleeve. At itsopposite end this counter-shaft connects by a spur-wheel g and pinion f"with the spurwheel b of the sleeve, so that the spur-gear f is drivenfrom the rotation of the sleeve.

The mandrel passes through central opening a of the head, as more fullyillustrated in Fig. 5. At opposite sides of the opening a the headcarries two revoluble feed-rolls 6 one upon each side of the mandrel.These rolls are adjusted by means of screws 77, and arecircumferentially grooved, as illustrated in Fig. 6, on semicircularcurves corresponding to the diametrical size of the mandrel,

their oifice being to feed the ribbon cl to and along the latter, saidrolls being rotated in the proper direction by motion-transmittingdevices hereinafter presentlydescribed. The feed-rolls b in addition totheir'feeding motion are revolved or carried bodily around the axis ofmotion of the mandrel and in the same direction with the rotating motionof the mandrel and the core carried thereon, but with only about halfthe speed of the mandrel, the latter in its revolutions slipping withinthe core to an extent corresponding to the difference of its revolublespeed as compared with that of the core. While, therefore, the coreformed upon the mandrel rotates more slowly than the mandrel, andconsequently more slowly than the sleeve and the reel, it follows that,the ribbon is wound upon the mandrel to an extent proportioned to theexcess of the speed of the sleeve and its mandrel over that of the core,which is retarded by the slower revolutions of the head with itsfeed-rolls. Meanwhile the slower motion of the head with its feed-rollsis sufficient to insure the winding thereon of a further number oflayers of paper, as hereinafter explained.

The feed-rolls, it will be observed, serve the double purpose ofregulating the revoluble speed of the core upon the mandrel and offeeding the core longitudinally along the latter.

The requisite motions are given to the feedrolls by appropriatemechanism, which, as shown in the drawings, is provided for operation asfollows: Supported by and rotating within a fixed annular bearing h is abarrel or hollow cone B, which has at one end a spur-gear 7?, while itsopposite end projects into the space a of the head A and preferablyworks smoothly therein, as indicated in Fig. 5. This smaller end of thebarrel has a spur-gear 7L4. Each feed-roll b has at one end of its shafta worm-wheel i.

The head A is provided with bearings 2' for short shaft-s k, each ofwhich has at one end aworm 7a, which gears with the adjacent worm-wheel2', while at'its opposite end is a spur-pinion 7a, which gears with thespurgear 7%. As the head A and barrel B rotate at dilferent rates ofspeed, the revolutions of the head carrying the spur-gear 75 around thespur-gear h of the barrel motion is transmitted through the worm-wheelsand to the feedrolls to feed the ribbon of material to and along themandrel, as hereinbefore'described. As the ribbon d passes from thesleeve to the barrel it is guided in its course to the mandrel by asloping or curved block j, carried by the sleeve and revolvedthereondary shaft D, parallel with the axial line of the mandrel,sleeve, head, and barrel, has a spur-pinion Z, which gears with thespur-gear 7b2 of the barrel. On this shaft is a ratchetwheel m. Pivotedon the same shaft is a swinging bar m, at one end of which is a springpawl m, which engages with the ratchet-wheel m. At the opposite end ofthis bar is an antifriction-rolleron, which receives the impact of a cam'n, on the shaft g, which, as hereinbefore explained, is rotated throughthe spur-gears b and g and pinion f". Pivoted in a fixed bearing is ahand-lever n, on which is an eccentric n Around this eccentric 71-passes a strap on the end of a longitudinally-mova ble rod 01 theopposite end of which is pivotally connected with the arm of theswinging bar m, this being preferably accomplished by a switch or ventin the end of the rod bearing against a pin it on the bar and pressedagainst the latter by a spiral spring n By manipulating the rod by meansof the hand-lever and its eccentric the lower or impact end of theswinging bar 772 may be moved more or less from the path of the cam 11,so that the action of the cam upon the swinging bar may be varied indegree with a proportionate change in the extent and duration of theaction of the pawl upon the ratchet wheel, a proportionate change in theextent of each impulse given to the rotation of the barrel, and aproportionate modification in the speed of the feed-rolls carried by thehead. In the operations above described the ribbon d is wound spirallyupon the mandrel as the sleeve rotates and the ribbon is fed thereto,the wound ribbon being moved along the mandrel as this feeding proceeds.This ribbon thus fed and wound upon the mandrel forms the core of thecompleted tube.

To complete the tube, it is essential that a further number of layers ofpaper or like material be wound around the core formed, as justdescribed, by the ribbon cl. This is provided foras follows: Placedsuitably adjacent to the mandrel is a paste-box E, in which is provideda paste-feeding roller 7', upon the shaft of which is a gear 1". Abovethis roller and geared therewith by a pinion r is a paper-feeding roll.9, and behind this latter are reels F, proportioned in number to thenumber of strips of paperor the like to be wound upon the core, as justexplained. In the drawings, Fig. 1, three strips are shown at u, and theapparatus is so arranged, as illustrated in said figure, that the stripsin passing to the core on the mandrel are oblique to the latter, thedegree of this obliqueness detel-mining the pitch at which the stripsare wound upon the core. The ends of the strips are at the outset ofthe-operation attached to the core, so that the strips are drawn to andwound upon the core as the latter revolves with the mandrel and iscarried longitudinally along the same, as hereinbefore explained. As thestrips pass over the pastefeeding roll their inner surfaces are coatedwith paste or adhesive material, so that when wound theyadhere to thesurfaces upon which at H in Fig. 11.

after cutting the tube, it is retracted to its lar sleeve, a mandrelrevoluble with the said they are wound. From the oblique position of thestrips with regard to the mandrel as they pass to the latter it followsthat the strips reach the mandrel in, so to speak, successive order, sothat while the firststrip in order is pasted direct to the surface ofthe core the second strip in order is wound upon and pasted to the outersurface of the second after the latter has been wound upon the core andthe third in like manner over and upon the second, so that the completedtube comprises,with the core and three strips, four plies of materialpasted or cemented one upon another. Inpractice it is preferable thatthe paste-feeding roller 1' be provided with a scraping-roller q toregulate the thickness of the paste thereon in feeding the paste to thestrips, and tension-bars 25 may be providedto regulate the tension ofthe strips as they pass from the reels to the paste-roller.

The paste-roller, the roller 3, and the scraping-roller should be gearedtogether, as shown To hasten the drying of the paste when the stripsofmaterial are wound upon the core, as described, a gas-burner G may bearranged in proper relation to the parts to dry the material as itpasses along the mandrel, as described. As the tube thus produced may becontinuous of a length to any degree proportioned to the length of theribbon and the strips of material fed'thereto, it is desirable that itbeautomatically cut into such lengths as may be desired for commercialor other uses. To provide for this, the invention includes themechanisms shown more in detail in Figs. 8, 9, and 10 of the drawings.

Mounted in bearings upon a suitable frame at that end of the apparatusremote from the sleeve and its adjuncts is a shaft I, which carries acircular saw K and has a pulley I,

through which from any suitable source motion'may be transmitted to thesaw K. This shaft is capable of a longitudinal movement in its bearingsand is connected,as presently explained, with the upper end of a "leverK,

the lower end of which works in connection with a cam K on acounter-shaft K which;

latter is driven through a pulleyL from any suitable operating power.proportions of the cam K should be such that when the cam actuates theshaft I to move the saw, as herein presently to be eX-' plained, the sawwill move at substantially the same speed and in the same direction thatthe tube moves along the mandrel. When, as presently explained, the sawis released original position by a spiral spring M, acting upon itsshaft.

Extended beyond the saw,as shown in Figs. l, 8, and 10, and supported insuitable guides or bearings are two parallel rods or bars R and R.

a and at another portion of its length a clutch b which connectswith'the upper end of a lever 0 the lower end of which has a stud Thespeed and On the bar R is a stop or shoulder R operatesthe lever c to.bring the stud'd in the path of the stud 6 the movement ,of the cam isstopped. The pulley L, it may bementioned, has a frictional hold uponits shaft, so adjusted that when the cam is free the pulley end rotatesthe latter; but when the cam is stoppedby the stud diet the lever thefriction is overcome and the pulley'runs free without rotating itsshaft.This is the condition when the saw is not in operation, and the bar. Risretracted to produce this result bya spring Sf", applied thereto, asindicated in'Fig. 8. Upon the bar R is provided a lever T,

whichat one end has'a contact-plate T,which contact-plate and swings thelever T. This,

latter then slides the bar Rto operate the lever 0' to bring its stud daway from the cam K which latter is then rotated and actuating the sawthrough the lever K carries thelatter along at the same speed as thetube. It is now necessary that the tube and saw be brought into suchrelation with each other that the saw will pass transversely through thetube to sever a section therefrom. To provide for this, the end of thetube which has passed from the mandrel is supported in a trough N,whichis carried on a framewhich is pivoted at its back, as shown at N inFig.

9. From this frame extends an arm N the free end of which rests upon acam 71 (shown in dotted 'outline' in Fig. 9) upon the shaft K of thecam. This cam t lifts the end portion of the tube against the saw, andthe latter being simultaneously carried along in the direction of thelength of the tube the end por tion of the latter'is cut squarely off ina plane 'at right angles to the length ofthe tube.
